No no. not have to be super high tech that you were thinking. There is this new tech that is under development at this time. Or well it was back when I found the article somewhere that a jeep mounted laser or something else that would shootdown incoming projectiles which essentially makes it "pre" forcefield tech.
Imagine this:

I mean miniaturizing is already beginning and if we can have a nano fiber armor I would think we can have a nanosize one of those that works against bullets. Do note I mean bullets. Which was why I said it may not work against plasmas or those particles gun thing.
Oh no mechs please. I agree with that. I think if I play xcom games, fan made or otherwise, on mechas i may as well play mech commanders....
What I meant was nanofiber armor with flight capabilities with one of those "forcefield" thingies built in for better protection.
then again those are just stupid ideas that I came up on the spot.
Edit: Okay, imagine that armor above with that miniaturized "pre" forcefield tech I was talking about.
